Everyday Astronaut explains the basic physics of rocket engines, the main engine cycles and fuel types, then compares SpaceX's methane-fueled full-flow staged combustion Raptor to other engines. It runs nearly 50 minutes with chapter markers.

Why HN likes it: HN commenters send people here as the best accessible starting point for understanding why Raptor and fuel choice matter for Starship.
